BY Z2 lOI United States Patent O 3,667,794 ANTI-INTRUSION DOOR SECURITY DEVICE Ben C. Lentz, Jr., Memphis, Tenn., assignor to Maggie Birdell Lentz, Memphis, Tenn. Filed May 7, 1971, Ser. No. 141,261 Int. Cl. Ec 17/36 U.S. Cl. 292-264 Claims ABSTRACT OF THE DISCLOSURE A device which may be attached to existing doors of a residence to safeguard against unwarranted intrusion while the occupants are sleeping or when answering a knock at the door, i.e., the device must be actuated by a person within the residence. The device includes a substantially indestructible tempered steel bar which bridges the crack of a door that is ajar. The bar is suspended from a pair of short chains which are inaccessible from the exterior side of the door. The free end of one of the chains is attached to a wedge which is removably received by a peculiar tamperproof receptacle. The receptacle is attached to a wraparound plate that is suitably fitted to the door panel by utilizing the existing door knob hardware to aid in the attachment thereof and for more positive reinforcement. The other chain has the opposite end attached to structure which is anchored into existing adjacent stud structure, i.e., 2" x 4" lumber or the like, so that the wall and/or the door panel would splinter before the device would become disengaged from either the wall or the door panel, irrespective of the amount of force being exerted from without. The door may be opened slightly to greet callers or guests while the device is engaged with absolute assurance that unwarranted intruders cannot break in, i.e., through the partially opened door.

BACKGROUND OF THE INVENTION (1) Field of the invention This invention relates to locking devices for a door.

(2) Description of the prior art Heretofore, anti-intrusion devices known to the applicant generally comprise two well known types. The first type is a sliding barrel bolt having one member attached to the door and the other member attached to the door molding so that when the door is closed, a bolt may be slipped from the one member and received into the other member. This type has an obvious disadvantage in that the device must be disengaged in order to answer a knock at the door, consequently permitting an unwarranted intruder to force the door and gain unauthorized entrance. A second disadvantage of the barrel bolt type is that even when the device is engaged, sufficient force can be exerted from Without to pull one of the members from the surface to which it is attached, or in the event the member attached to the molding is well anchored thereto, the relatively thin molding may literally be ripped from the adjacent jamb.

The second type includes a chain having one end fixed to the molding and the other end provided with a dog which may be removably received in a catch which is attached to the door, or vice versa. This type obviates the aforementioned first disadvantage, i.e., the door may be slightly opened to greet callers or guests while the device is engaged. However, the aforementioned second disadvantage pertaining to the first type also pertains to the second type, i.e., extreme force exerted on the outside of the doormay rip the screws from their holding or the molding. maybe rippedfrom the jamb. Additionally, .a

3,667,794 Patented June 6, 1972 SUMMARY OF THE INVENTION The present invention is directed towards overcoming the disadvantages and problems relative to previous antiintrusion devices. The concept of the present invention is to provide a device which may be attached to existing doors of the residence to safeguard against unwarranted intrusion, particularly while the occupants are sleeping or when answering a knock at the door, i.e., the device must be actuated by a person within the residence.

The device includes a substantially indestructible tempered steel member or bar which bridges the crack of a door that is a ajar. The bar is suspended from a pair of short chains which are inaccessible to an intruder from the exterior side of the door, i.e., the bar is the only part of the device accessible through the crack and it is particularly designed to resist the usual cutting devices such as hacksaws or bolt cutters and the like. The free end of one of the chains is attached to a wedge which may be removably received by a peculiar tamperproof receptacle. The receptacle is attached to a wraparound plate that is suitably fitted to the door panel by utilizing the existing doorknob hardware to aid in the attachment thereof, resulting in more positive reinforcement or extremely strong structure. The other chain has the opposite end attached to structure which is deeply anchored into the existing adjacent stud structure, i.e., inner framework of the building which usually is 2" x 4" lumber or the like. In other words, the device is so strongly anchored to both the door panel and the wall that regardless of the amount of force exerted from without the device will not give way or become disengaged at the point of attachment to the building. In fact, the door panel and/or the wallof the building would splinter before the device would fail. The door may be opened slightly to greet callers or guests while the device is engaged with absolute assurance that an unwar ranted intruder cannot break in, i.e., through the partially opened door. Additionally, the wraparound plate structure prevents the bar or the chain from gouging the door panel even after prolonged and abusive use.

Further, the device, being positioned on the door at the same level as the door knob and the door latch, will impede the use of jimmy tools or the like which may be used in an attempt to pick or disengage the device, i.e., through the crack between the door panel and the adjacent facing molding, the crack being approximately to 1".

The tolerances in conjunction with certain structure of the device are important features of the invention. This latter feature will be more apparent when the remaining structure has been fully disclosed later in the specification.

BRIEF DESCRIPTION OF THE DRAWINGS appropriate portions of the door panel, certain associated FIG. 4 is a sectional view taken as on of FIG. .1.

DESCRIPTION OF THE PREFERRED EMBODIMENT The anti-intrusion door security device 11 of the present invention is intended to be attached to existing structure of a residence. The existing structure alluded to includes stud structure 13 defining a rough opening in a wall 15, i.e., only one stud 13 is shown, for receiving the usual jambs 17 of a door case, only the keeper iamb 17 is shown, a striking plate 19' fixedly attached to the jamb 17, a door panel 21 hingedly attached to the other jamb (not shown), interior facing molding '23 fixedly attached to the jambs 17, and a striker bolt 25 attached to the door panel 21 for latching engagement with the striking plate 19 and being operable by a shaft 27 having an interior door knob 29 fixedly attached at the one end thereof.

Preparatory to installing the device 11, a door stop 31 attached to the keeper jamb 17 preferably is removed and the keeper jamb 17 and the stud structure 13 are provided with a first bore 33 at a. height substantially equal to the height of the striking plate 19. Additionally, the interior facing molding 23 and the stud structure 13 are provided with a second bore 35, i.e., the second bore 35 being at the same level as the first bore 33 intersects the first bore 33 centrally of the stud structure 13. It should be understood that usual construction techniques include a sheetrock paneling 37 or the like which is fixedly attached to the stud structure 13. In this event, the second bore' 35 additionally extends through the paneling 37, as illustrated in FIG. 3 of the drawings.

Additionally, the hardware associated with a residential door usually includes an annular plate 39, having a large concentric aperture 41 enabling the shaft 27 to pass therethrough and a pair of smaller apertures 43 for receiving screws (not shown) in a manner obvious to those skilled in the art. However, the plate 39 prevents an intruder from pulling the hardware outwardly from the door. The significance of mentioning the plate 39 will be more apparent when the remaining structure of the device 11 has been disclosed.

v The device 11 in general comprises an anchor rod 45, an anchor arm 47 having an externally threaded portion 47 adjacent the inner end thereof for threaded'engagethe line IV-IV verse aperture 65, i.e., the aperture 65 receives the anchor rod 45. The inside diameter of the sleeve 63- is greater than the diameter of the anchor arm 47 and the length of the sleeve 63 exceeds the length of the anchor arm 47. The outside diameter of the sleeve 63 preferably is substantially equal to the diameter of the second bore 35, i.e., the bore receives the sleeve 63 snugly and the arm 47 has a concentric spaced apart relationship with the sleeve 63.

The device 11 also preferably includes a finishing collar 67 which is threadedly received by the outer end of the sleeve 63, i.e., the tubular inner end 67' of the collar 67 is provided with exterior threads, and the outer end the sleeve 63 is provided with matching interior threads for receiving the collar 67. The collar 67 includes an outwardly directed flange portion 67" which contiguously engages an appropriate portion of the face molding 23.

It should be understood that the door stop 31 may conveniently be replaced after the anchor rod 45 and the anchor arm 47 are positioned as just described, i.e., the door stop 31 obscuring the first bore 33.

Particular attention is now directed toward the preferred method for attaching the chain 53, 55 to structure previously described. A plurality of steel taper pins 69, having a scoured surface thereon, are used for this purpose. More specifically, the opposite ends of the bar 51 are provided with a pair of clevises 71, 73 for respectively receiving one of the ends of the chains '53, 55. Additionally, the clevises 71, 73 are provided with transverse apertures 75 for receiving a pair of the pins 69, i.e., one of the pins 69 captures the free end of the chain 53 within the clevis 7.1 and the other pin 69 captures the free end of the chain 55 within the clevis the wedge lock 59 is provided with a second bore 83 ment with a transverse aperture 49 in the anchor rod 45, i.e., the anchor rod 45 being received in the first bore 33 and the anchor arm 47 being received in the second bore 35. Additionally, there is provided a linking assembly 50, which preferably includes an elongated rigid member bar 51 depending from first and second chains 53, 55, i.e., one of the ends of the first and second chains 53, 55 respectively being attached to opposite ends of the bar 51, in a manner yet to be disclosed so that there is a flexible portion, i.e., chains 53, 55 and a rigid portion or member 51 of the linking assembly 50. Further, the other end of the first chain 53 is attached to the outer end of the anchor arm 47, in a manner yet to be disclosed. Further, a platelike panel engaging member 57 is fixedly attached to the door panel 21, in a member yet to be disclosed. Further, a cubelike wedge lock 59 is fixedly attached to the other end of the second chain 55 and an elongated co-acting wedge lock receptacle 61 is fixedly attached to the member 57 and removably receives the wedge lock 59, i.e., when the wedge lock 59 is placed within the receptacle 61, the door 21 may be swingingly opened slightly, establish ing a crack approximately %"-1", between the door 21 and the facing molding 23 with the bar 51 bridging the crack. Thus the device 11 precludes unwarranted intrusion. a

The device 11 preferably includes a tubular sleeve 63, having the inner end 63' thereof provided with a transperpendicular to the bore 81 and intersecting the bore 81, as best viewed in FIG. 2 of the drawings. It should be observed that the bores 81, 83 preferably do not extend all the way through the wedge lock 59. The bore 83 receives one of the pins 69, i.e., the pin 69 capturing the end of the chain 55 in like manner as previously described for the clevis 71, etc. If desired, other means for attaching wedge lock 59 to chain 55 may be provided without departing from the spirit and scope of the present invention.

The platelike panel engaging member 57 includes a first portion 85 and a perpendicularly disposed second poriton 87. The first portion 85 contiguously engages the interior surface of the door panel 21 adjacent the inner door knob 29. The first portion 85 is provided with an aperture 89 for receiving the shaft 27, i.e., the aperture 89 being coincident with the previously disclosed aperture 41 in the plate 39. Additionally, the first portion 85 is provided witha pair of apertures 91, i.e., apertures 91 being in alignment with'the previously described apertures 43.

The second portion 87 of the member 57 contiguously engages a third surface 93 of the door panel 21, i.e., the third surface 93 being between the interior and exterior surfaces of the door panel 21 adjacent the keeper jamb 17. The second portion 87 is provided with an aperture 95 for allowing the striker bolt 25 to pass therethrough.

In this regard, it should :be obvious to those skilled in the art that usual hardware associated with a residential door includes a striker bolt guide (not shown) but which comprises a platelike member having apertures for receiving screws which are driven into the door panel 21, i.e., the heads thereof being flush with the third surface 93.

It should be pointed out that prior to installing the member 57 to the door panel 21, the inner door knob 29, the annular plate 39, and the striker bolt guide (not shown) preferably are first removed. Additionally, it may be desirable to now accomplish any necessary routing of the panel 21 in the event a professional flush surface is desired between the member 57 and the door panel 21, i.e., depending upon the thickness of the material selected for the member 57. Regardless, the third surface 93 preferably is routed so that the striker bolt guide (not shown) may be replaced over the second portion 87 so that suitable clearance exists between the striker bolt guide (not shown) and the striking plate 19. It should be explained that the second portion 87 is provided with a pair of apertures (not shown), one above and below the aperture 95 and in alignment with the previously described apertures in the striker bolt guide (not shown) for receiving the just-mentioned screws (not shown), i.e., having their heads flush with the third surface 93.

Particular attention is now directed toward the construction details of the wedge lock receptacle 61. The receptacle 61 includes elongated boxlike structure 96, i.e., a pair of vertically disposed parallel spaced apart rectangular shaped platelike members 97, 99 which are joined at the lower ends thereof by a substantially square shaped platelike member 101 and are joined at the upper ends thereof by a horizontally disposed rectangular shaped platelike member or an overhang canopy 103. The boxlike structure 96 is fixedly attached to the platelike panel engaging member 57 in any well known manner, e.g., I prefer that the first portion 85 of the member 57 be provided with a pair of slots 105, 107 (FIG. 3) and that the members 97, 99 respectively include tab portions 109, 111 which respectively are received in the slots 105, 107. Additionally, the tab 109 is bent so as to be perpendicular with the member 97, as shown in FIG, 3, the tab 109 is welded to the underneath surface of the first portion 85, and the tab 111 is welded to the underneath surface of the second portion 87 as symbolically shown. In other words, the boxlike structure 97 including the members 97, 99, 101, 103 provides an elongated outwardly directed opening, when attached to the first portion 85 in the manner just described.

The receptacle 61 additionally includes a platelike capping member 113 which is positioned adjacent the elongated boxlike structure 96 so as to partially enclose the just-described outwardly directed opening, i.e., the remaining portion of the opening defines a rectangular socket 115 for removably receiving the wedge lock 59. Appropriate outer margins of the capping member 113 engage appropriate portions of the outer surface of the members 97, 99, 101 and are fixedly attached thereto in any well known manner as by welding or the like.

In other words, the capping member 113 has a width substantially equal to the width of the boxlike structure 96, i.e., substantially equal to the spaced apart distance of the members 97, 99 and a predetermined length. Additionally, the capping member 113 is arranged on the boxlike structure 96 so the uppermost edge thereof and the adjacent portions of the boxlike structure 96, i.e., upper portions of the members 97, 99 and the overhang canopy 103, established the rectangular socket, i.e., the socket 115 having a width greater than the height, for reasons yet to be disclosed.

The capping member 113 is provided with a vertical slot 117 centrally thereof for allowing the passing therethrough of a portion of the chain 55 as the wedge lock 59 is caused to move to and fro within the boxlike structure 96, i.e., from a fully engaged position shown in FIG. 2 wherein the wedge lock 59 is resting on the member 101 upwardly to a midposition yet to be fully disclosed but character referenced by the numeral 59 and 6 outwardly from the socket as character referenced by the numeral 59".

It should be understood that while the receptacle 61 was hereinabove described as having separate members fixedly attached one to the other as by welding or the like, it is intended that an integrally formed receptacle '61 is within the spirit and scope of the present invention, i.e., platelike sheet metal may be pre-cut and suitably bent to define the structure as above included in the receptacle 61, in a manner obvious to those skilled in the art.

The device 11 additionally includes an anti-withdrawal means comprising a pair of nibs 119, 121 respectively positioned alongside the vertical slot 117 adjacent the uppermost edge of the capping member '113. The nibs 119, 121 project inwardly of the boxlike structure 96 so that the wedge lock 59 must be urged inwardly to pass beyond the nibs 119, 121, i.e., like that shown in FIG. 2 and character referenced by the numeral 59', to permit movement thereof into the socket 115 for withdrawal thereof. In other words, the nibs 119, 121 impede the removal of the wedge lock 59 from the receptacle 61 by :1 person positioned adjacent the interior side of the door panel 21 and preclude the removal of the wedge lock 59 from the receptacle 61 by a person positioned adjacent the exterior side of the door panel 21.

Particular attention is now directed toward the construction details of the wedge lock 59. The wedge lock 59, being formed from a block of steel or the like, has opposite surfaces 123, thereof preferably in the shape of a square and the remaining four surfaces 127 thereof preferably in the shape of rectangles respectively having the largest dimension thereof substantially equal to one side of the square surfaces 123, or 125. The uppermost surface, or the overhang canopy 103, of the boxlike structure 96 is a rectangle, i.e., the length of the overhang canopy 103 is substantially equal to one side of the square surfaces 123 or 125 of the wedge lock 59 and the width thereof is of a predetermined size, i.e., sufiicient in width so that the vertical distance between the uppermost edge of the capping member 113 and an extension of the plane of the overhang canopy 103 is less than the dimension of one side of the square surfaces 123 or 125, but the distance between the distal or outer edge of canopy 103 and the upper edge of capping member 113 is greater than the smaller dimension of the remaining four surfaces 127. In other words, the dimensions of the socket 115, the overhang canopy 103, the length of the capping member 113, and the surfaces 123, 125, 127 of the Wedge lock 59 have close tolerances so that the wedge lock 59 must be rotated about a horizontal axis to a diagonal position character referenced by the numeral 59" in FIG. 2 of the drawings with respect to the door panel 21 in order to be inserted into or withdrawn from the socket 115. Thus, this further precludes the removal of the wedge lock 59 by a person positioned adjacent the exterior of the door panel 21.

Additionally, a close tolerance in conjunction with the length of the chains 53, 55 is an important feature of the present invention, i.e., the length of the chains 53, 55 is such that when the wedge lock 59 is full engaged as shown in FIG. 2, the door 21 may be swingingly opened slightly establishing a crack, approximately %"-l" between the door 21 and the facing molding 23. In this regard, it is desirable that when the wedge lock is in the position depicted by the numeral 59 in FIG. 2 of the drawings, there preferably would not be a crack between the door 21 and the facing 23. Further, when the wedge lock is in the position depicted by the numeral 59" in FIG. 2 of the drawings, the door 21 preferably must be fully closed, i.e., the striker bolt 25 being in a position to engage the striking plate 19 as shown in FIG. 3 of the drawings.

FIG. 2 shows a modified embodiment of the linking assembly 129, which, if desired, may be utilized in place of linking assembly 50. Linking assembly 129 includes a single chain 131 for the flexible portion and a rigid sleeve or tube 133 for the rigid portion of the linking assembly 129. Tube 133 is preferably formed of the same material as heretofore described for bar 51. Chain 131 extends through tube 13-3 and is attached at the opposite ends thereof to Wedge lock 59 and anchor arm 47 by suitable means, as for example, like that previously described for the preferred embodiment. a

Although the invention has been described and illus trated with respect to a preferred embodiment thereof, it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of the invention.
